Yes! All of our Pennies from Heaven are made from real United States pennies.
The United States one-cent coin (symbol: ¢), often called the penny, is a unit of currency equaling one one-hundredth of a United States dollar. The coin is 0.75 inches (19.05 mm) in diameter and 0.0598 inches (1.52 mm) in thickness. Its weight has varied, depending upon the composition of metals used in its production.
The U.S. Mint's official name for the coin is "cent" and the U.S. Treasury's official name is "one cent piece". The colloquial term penny derives from the British coin of the same name, which occupies a similar place in the British system. In American English, pennies is the plural form (the plural form pence—standard in British English—is not used in reference to American coins).
